I kept getting surprised by my AI API bills, so I built a tracker in one night

I use OpenAI and Claude in a few side projects. Every month I'd open the billing pages and think "wait, how did it get that high?" Each provider has its own dashboard, its own billing cycle and its own way of reporting costs, and none of them tells you when something starts running away.

So I built AI Spend Tracker: https://aispendtracker.online

What it does

Connects to OpenAI, Anthropic, Google Gemini, xAI (Grok), OpenRouter and DeepSeek with read-only keys. It can see your usage but can't spend anything.
Puts your daily spend from all of them into one dashboard.
Lets you set a monthly budget and get pinged by email, Slack or Discord when you cross 50%, 75%, 100% or a point you choose.
Sends an hourly burn-rate alert if spend jumps faster than your limit. Someone on X said "a ping when one agent loop burns $50 in an hour is what would get me to sign up," so I built it the same day.

How it works under the hood

Starlette + Postgres, hosted on Render.
Each provider reports costs differently, so every fetcher normalizes into the same {date: usd} shape before anything is saved. OpenAI and Anthropic have usage and cost APIs. Gemini goes through the Google Cloud billing export in BigQuery. xAI and OpenRouter use management keys. DeepSeek only exposes a balance, so spend is the drop in that balance between checks.
An hourly job pulls fresh numbers and checks budgets and burn rate.

Try it

There's a free plan and a live demo on the homepage, no signup needed. Pro has a 3-day trial.

I'd love honest feedback: what's missing that would make you actually use this?

If you've built anything on top of GPT, Claude or Gemini, you've probably had the moment: everything's working, users are happy, and then the bill arrives and it's way more than you expected.

The tricky part isn't the cost itself, it's not seeing it coming. Each provider shows spending in its own separate dashboard, so it's easy to miss what's adding up until the bill lands.

So I built AI Spend Tracker.

What it does

Connects to OpenAI, Anthropic, Gemini, Grok, OpenRouter and DeepSeek, plus any other tool you enter by hand
Shows one monthly total across all of them
Sends a heads-up by email, Slack or Discord at the budget points you choose
Flags sudden spikes and warns you if you're on pace to go over

A fun technical bit

Every provider reports spending differently. OpenAI and Anthropic have cost report APIs. Gemini doesn't have a simple one, so it reads your own Google Cloud billing export. DeepSeek only shows your balance, so the tracker watches how much it drops between checks.

There's a live demo on the homepage, no signup needed: aispendtracker.online

It's free for one provider. I'd love to hear what you'd want it to track next!
